DECISION

and 4 other applications
(see appended table)
The European Court of Human Rights (Second Section), sitting on 21 May 2026 as a Committee composed of:
 Stéphane Pisani, President,
 Juha Lavapuro,
 Hugh Mercer, judges,
and Viktoriya Maradudina, Acting Deputy Section Registrar,
Having regard to the above applications against the Republic of Türkiye lodged with the Court under Article 34 of the Convention for the Protection of Human Rights and Fundamental Freedoms (“the Convention”) on various dates indicated in the appended table,
Having deliberated, decides as follows:
FACTS AND PROCEDUREThe list of the applicants is set out in the appendix.
The applicants’ complaints under Article 5 § 3 of the Convention concerning the lack of relevant and sufficient reasons for their detention, were communicated to the Turkish Government (“the Government”), who submitted observations on the admissibility and merits. The observations were forwarded to the applicants, who were invited to submit their own observations. No reply was received to the Registrar’s letters.
By letters dated 18 December 2025, sent by registered post, the applicants were notified that the period allowed for submission of their observations, had expired on 13 October 2025 and that no extension of time had been requested. The applicants’ attention was drawn to Article 37 § 1 (a) of the Convention, which provides that the Court may strike an application out of its list of cases where the circumstances lead to the conclusion that the applicant does not intend to pursue the application. The applicants received these letters on the various dates, however, no response followed.
THE LAWHaving regard to the similar subject matter of the applications, the Court finds it appropriate to examine them jointly in a single decision.
In the light of the foregoing, and in the absence of any special circumstances regarding respect for the rights guaranteed by the Convention and the Protocols thereto, the Court, in accordance with Article 37 § 1 (a) of the Convention, considers that it is no longer justified to continue the examination of the applications.
Accordingly, the cases should be struck out of the list.
For these reasons, the Court, unanimously,
Decides to join the applications;
Decides to strike the applications out of its list of cases.
Done in English and notified in writing on 11 June 2026.
